The problem is hopefully attached, I had to take a screen shot.
I understand the process of taking the derivative of position to get velocity.
*refer to derivative rules.... for example r(x)=2x^2-6x+8 therefore r`(x)=4x-6
The Attempt at a Solution
I am stuck with what to do with the "1/s"
The correct answer is 2.8m/s
Thank you so much in advance.
